含茂基及邻取代苯甲酸基钕（Ⅲ）有机化合物的合成

Synthesis of Organonodymium(Ⅲ)Complexes Involving Cyclopentadienyl and o-Substituted benzoxy Ligands

本文合成了八种新的茂基钕邻取代苯甲酸衍生物：Ｃｐ＿（３－ｎ）Ｎｄ［Ｏ＿２ＣＣ＿６Ｈ＿４（０－Ｚ）］＿ｎ（ｎ＝１，２；Ｚ＝ＯＭｅ，Ｃｌ，Ｂｒ，Ｉ；Ｃｐ＝Ｃ＿５Ｈ＿５）。由于邻位取代基中配位原子Ｘ（Ｏ，Ｃｌ，Ｂｒ，Ｉ）与中心Ｎｄ￣（３＋）之间具有配位作用，增加了铁的配位数及空间饱和性，提高了这类化合物的稳定性。这些化合物均经过元素分析，红外光谱，质谱及光电子能谱鉴定。

eight new o-substituted benzoxy complexes of Neodymium with cyclopenta-dienyl ligands,Cp_(3-n)Nd[O_2CC_6H_4(o-Z)]_n(n=1,2;Z=OMe,Cl,Br,I;Cp=C_5H_5),have been synthesized,As the donor atom X(O,Cl,Br,I)of o-substituted benzoxyforms chelation with centre Nd￣(3+) in the complexes,so it satisfied the requirment of co-ordination satruation of neodymium ion,and increased stability of these complexes.Their structures were identified by elemental analvsis,IR,MS and XPS.
